ray marching is a rendering technique that works by marching a ray through a scene, and drawing a pixel if it hits something. it's commonly used in real-time applications for volumetric rendering - smoke, water, fog, atmospheres, clouds, dust, etc. - but is also great for rendering fractals and other mathematical objects. raymarching is typically accelerated through the usage of distance functions - if you know the distance to the nearest surface, regardless of what surface that is, you know how far you can march a ray without hitting anything.
inigo quilez explains it better than I can

and some examples, with accompanying GLSL code

inigo quilez has tons of great articles on his website about distance functions, SDF and ray marching too. he's the co-founder of shadertoy too btw
